To all whom it may concern:

Be it known that l, nn'r lFnoon, a-

' binder for coatin and bonding coated tabrics for frictional and wearing purposes.

According to this invention, a cementitious substance or binder for coating and bonding fabrics for frictional and wearing purposes, comprises Il1lflil1 gum and rubber in suitable proportions. With the door gum and rubber, ll may, if desired, incorporate other binding agenmfluch as e, g. those described in specifications of British Patents Nos. 4627 or 1909 and 164M752, or the well-own phenol-aldehyde condensation products, glue, casein, chloronaphthalene substitution products, or sodium or potassium or other silicates or mixtures thereof, in about the proportion of one part of any, or a mixture of two or more, of such other binding agents to three parts of dammar and rubber.

Conveniently, the improved cementitious substance may consist of a mixture of approximately two parts of dammar gum) and one part of rubber with suitable quantities of linseed or tung oil, a suitable drier and the other binding agent or agents when such is or are employed.

The following examples of the improved cementitious substance or binder have been found to give excellent results, the parts being by Weight.

Example 1.

Parts. Dammar gum 20 Rubber 10 Prepared linseed or tung oil 20 Mineral naphtha, benzol or other suitable solvent hplnlication filed March 211, 119%. Serial No. 626,642.

With 100 partsof mixture (2;) are incorporated 200 parts of mixture (a),

By the term prepared oil, it mean oils prepared by the well known method of addinmctallic drier-s thereto.

\7 hen the finished fabric is to be coloured, I may dye the fabric in the piece, or dye the yarn before weaving, or the fibres in I the mass, and correspondingly colour the binder. Alternatively, the colouring of the finished fabric ma, be efiected solely by the colouring oi the inder.

The fabric maybe coated are, binder under atmospheric or elevated pressure or in vacuo. -Alternatively, the fabric may be coated by irictioning the binder into it, and I may employ any or the well known methods and means used in trictioning rubber and waterproofing compounds into fabrics. Conveniently, ll may pass the fabric one or more times between rollers rotating at difierent speeds and apply the binder to that surface between which and the core5 responding roller relative movement or slip takes place. The roller may exert any dcsired pressure on the fabric to force the binder thereinto and consolidate same, and the irictioning may be efi'ected under applied heat (in which case the rollers may conveniently be hollow and be heated internally by steam or otherwise suitably), or under the heat due to frictioning onl After coating, the fabric may be air dried 9 for a suitable period and be subsequently a baked or stoved at a comparatively low temperature (e. g. about -180 F.) for about 12 hours.

What I claim as my invention and desire 1 to secnre'by Letters Patent is l. A composition for coating and bonding five parts.

2. A oompositionfor coating and bonding fabric consistingof substantially two parts of dam narfguin, substantially one part of rubber; substantially two parts of prepared linseed oil, and substantially fi'veparts of a mineral hydrocarbon solvent.

tion fabric cons1st1ng of a fabric base bonded and coated with dammar gum, rubber, a drying 011, and a solvent in substant ally the 3. As a new article of manufacture, a fricfollowing proportions, danimar'guin two parts, rubber one part, oil two parts, and solvent five parts. i

In witness whereof I have hereunto set my hand.
